I have a Silverlight web project where I apply the MVVM pattern. In my entire solution I have 4 projects.
Project "A3", which contains all of my Views and ViewModels.
Project "A3.Web", which contains my main html files, images, sound files, etc.
Project "A3Lib", which contains my XAML binding converters and other helpful classes that I created.
Project "A3Lib.Web", which contains the Data Models and Domain Logic.
All of my entity models are inside my DataModels folder and all of my Domain Service server side code is inside the DomainLogic folder. I created a new folder inside the DataModels folder named "Common".
So when I want to add the data model to my VM, I tried "using A3Lib.Web.DataModels.Common;" and that did not find the namespace.
Issue: when I add a new folder and a new entity model to the DataModels folder, I do not see the namespace in my View or ViewModel in the "A3" project.
However, I already have existing code there (was added by someone else) and the models he added show perfectly fine (when doing using ...... in the View or VM).
I checked web.config to make sure the connection string is there and it's correct. I also tried to add a brand new context to the base class of the project (where other contexts are) and that did not help. My project simply cannot resolve or see the data model namespace that I create.
Thanks

The Silverlight app sees the models and namespaces from the server-side project through the generated code - you should see it in the Generated_Code folder of your A3Lib project. If it is not there, then the proxy classes are not being generated on build. A couple things to check:
class is not private (hey - sometimes it's the simple things)
if using Domain Services, the service needs to have at least 1 method that returns an IQueryable or IEnumerable (even if method returns null) in order to see the class in the Silverlight-side domaincontext
if the class is just a utility class that you want to share with the client, save the file as classname.shared.cs, and the proxy will pick it up.
make sure the project references are to the projects and not (possibly older) .dlls in another location.
That's all I've got based on the info provided.

I am wprking on a project and I have 2 projects in one solution. I added my WCF project and inside it I added an entity framework. Also in Service1.svc I can reach the classes and use them for saving like
public bool saveuser(User user)
{
}
For example User is the name of my database and Its pretty fine working in WCF part but at WPF part Im trying to access this class again to fill this class's object and I using MyClass.ServiceReference1; on the top and Inside one of my method I can not reach this class. What should be the solution why I can not access my class instead I added this WCF service as a service reference and enabled async operations.
Im newbie and thanks

I have a Solution with different Projects:
A Silverlight Class Library:
- In this I have a "Link" to the CS File with Attribute wich is used on a DTO
- In this Class there is also a modified Datagrid wich uses the Attribute
A RIA Class Library:
- It has a Link to a web project, and loads my DTO class
- It also has a Reference to the class Library defined before!
A Silverlight Project:
- This is my runtime and loads dynamicly the RIA Project.
Now to the Problem:
The DTO in the RIA Project does not have the Attribute defined on the real DTO! When I move the Attribute to the RIA-Class-Library, it works, but this is not possible, because then I have no access to the attribute from my normal Class Library!
when I did this bevore, using a normal RIA-Project instead of RIA-ClasLibrary, there it worked. It did find the types from the Referenced DLLs.
But now I need the other aproach.
Anyone can help?
Ah, the error code is: The attribute '...' is not visible in the client project '...'
I got it now! Seams like i referenced two Versions of Microsoft.Iteractivity, and this broke Ria from finding the Attributes
I have created a class so that I can bind it to a combo box. I have a solution where there are two projects test and test.web. In the test.web I have added a new class so that I can bind it to a combobox. In the same test.web I have created few entities with help of ADO.net Entity Object Generator and those classes can be seen when I am trying to add my class as resource to a grid. Why not my class?
When I add my class as resource I get error the type '..' was not found. Verify that you are not missing assembly reference....
Finally I found the answer. My understanding of SilverLight was wrong as I am still learning it. I found out that I cannot directly access all the class in the model on the client side directly. They all should be exposed using DomainService and DomainService is the thing which you can access on the client side, if you have to access your class expose that through DomainService.
I've split out my domain services into a separate WCF RIA Services Class Library project. However there now seems to be a problem with using the resource strings in the client side library.
e.g.
The client project library has generated code like this:
[DataMember()]
[Display(Description="FullNameDescription", Name="FullNameLabel", Order=-1, ResourceType=typeof(MetadataStrings))]
[StringLength(255, ErrorMessageResourceName="BadFullNameLength", ErrorMessageResourceType=typeof(MetadataStrings))]
public string FullName
{
// ...
}
where MetadataStrings is a resource file in the class library. This class library is then referenced by the silverlight project.
But the meta attributes that use ResourceType cause the designer to throw an exception when opening a view and at runtime cause a MissingManifestResourceException.
If I comment out the attributes and rebuild it all works fine. So something is not right with the resources being in another assembly i'm guessing?
Edit: Nevermind finally got this working, problem was that i renamed my class library projects and the namespace of the resource file was wrong. 3 days wasted.
I have the following Ria Service define:
namespace SilverlightTest.Web
{
[EnableClientAccess()]
public class ContactService : LinqToEntitiesDomainService<AdventureWorksEntities>
{
public IQueryable<Contact> GetContactSearch(string lastName)
{
ContactRepository rep = new ContactRepository();
return rep.SearchByLastName(lastName);
}
}
}
When I compile the solution, my SilverlightTest project does create the SilverlightTest.Web.g.cs file and the appropriate Context objects are created when I look at it. However, when I attempt to import the SilverlightTest.Web namespace to access the Data Context class for the above service, it says it cannot find the Web namespace.
The only difference I can see between what I'm doing and many examples that are out there on the web is that my AdventureWorksEntities data context is located in a separate business object dll. I tried to query the context directly instead of using the Repository Pattern I'm attempting to do and it also isn't work working.
Any ideas? Is it possible to have Ria Services access a separate DLL handling data access or does it HAVE to be in the same project?
I've been able to put the Ria service in a separate project before, although I do remember having issues. Not sure exactly what it was, but I would check two things: your references and your web.config (in the hosting website). When you add a ria service to a web project it does some things behind the scenes that wire everything up correctly.
Could try adding a service to your web project temporarily and see what it adds.
It seems that Resharper does not recognize the .gs files and their name spaces. If you disable R# or just code without intelisense it works.
